Last nigh, we tough we found the cause of our problems with the hydrophones. We thought we found it and that we applied the necessary patch. Unfortunately, the test of this morning brought use back directly to the startup position. To big problems, big means. This afternoon, we revisited all the hydrophones and their physical interfaces. We have still been able to test the navigation. Like every day at the Transdec, we are really surprised with the data that we receive. With the exact same configuration as yesterday, the Sonar does not give us the same results. What was yesterday…

After we have fixed the thrusters (by changing the navigation board), we have been able to do two tests in a row at 10am35 and we had a test of 1h15. The goal of the test was to acquire the data with the sonar and the vision on the buoys and the fence. We also took advantage of Dave presence to go through the gate and qualify for the semi-finals. We acquired enough data to be able to work on the logs and answer the question that we have: The value of the DVL drift Are the walls visible with…

Today, we worked on improving our effectiveness during the tests. The hotel wifi being not as good as we would like it to be, we had to setup a Git server on a raspberry-pi so we can access our code base without the internet. We did a few scripts to ease the configuration changes on the workspace. Alexi worked on the CAN UI in order to increase the rapidity of the latter and ease its usage during the debugging of the hydros. Also, ROS allows us to log the messages the go through the network during the execution time. Pierluc…

First full day in San-Diego for the team. Everyone agrees that California’s weather is completely unique. For breakfast this morning: coffee and getting the submarine. We have no time to waste. Unless a little inconvenient, the sub arrived to our room the fun part could finally begin. On the software side, the team cleaned the code and we developed a user interface for the mapping system to modify the settings and observe the effects easily. On the mechanical and electrical side, we reassembled le submarine. Everything is well … but we need to mention Jéremie’s cold sweat when he found…

Hey folks! As you may have noticed, we recently encountered technical issues with our website. We finally decided to re-do it from scratch, and here we are! Our new website is finally ready.
